So I'm a newbie and I was sitting looking at the beer the other night. Its been in the fermenter for about 12 days. SA-05. The krausen rose and fell and now the surface has a little pond scum on it but nothing else. There is also no airlock activity. I took at sample at 7 days and it had gone from 1.060 to 1.013. I had to move the fermenter around and after I did I started getting a good amount of airlock activity. So I watched and white globs (assuming yeast) would float like rockets up from the bottom. Then something would squirt out and the glob would drop back to the bottom. Kind of amusing to watch.

What are they doing?

Where in the life cycle does this happen (if its normal From everything I've read I know to just shut up and take gravity readings a couple days apart to determine if its done, but this is just for my personal edification.

Through some home brewing experimentation, I have come to the conclusion, that the activity that you are seeing in your carboy is actual a precise replica of the primordial ooze that all of the life on earth evolved from billions of years ago. Basically We all evolved from a sort of primordial beer, most likely a stout or porter style.
